A typical baby monitor set consists of two parts: a radio transmitter and a portable receiver. The radio transmitter must be positioned 8 to 10 feet away from your baby's crib. Then again, you can always position it closer to the baby for better reception of sounds. The signal picked up by the radio transmitter is then passed on to the portable receiver, which can be carried effortlessly around the house. In babies, this could be a congenital defect. Central apnea is very rare in adults but quite common in babies especially those who were born prematurely. Unlike obstructive apnea, this can happen at any time of the day. The third type of apnea is called mixed apnea. This condition is the combination of obstructive apnea and central apnea.

In the case of using baby monitors in blocks of flats with a dozen or more tenants, the devices may encounter several problems which include interference. But despite such circumstances, it is good to know that technology has managed to make life easier by giving busy moms and dads the option keep an eye on their precious little one even when they aren t in the same room. And no matter how busy life may get, it is at least assuring to a lot of families that there is a gadget available that truly contributes to their peace of mind and adds to the precautions that parents place in providing for their child s safety. By means of the receiver, you will be able to monitor awakenings in the middle of the night.

At daytime, a baby monitor also provides you with an enormous freedom to do other things during your baby's naptime.
